Exercise 2 (order statistics of i. i.d. exp rvs). one hundred light bulbs are simultaneously put on a life test. suppose the lifetimes of the individual light bulbs are independent exp(λ) rvs. let tk be the kth time that some light bulb fails. we will find the distribution of tk using poisson processes.

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!

its a 5.5 n

glad that
